This application claims priority to U.S. Application No. 62/608,493, filed Dec. 20, 2017 and U.S. application Ser. No. 16/224,423, filed Dec. 18, 2018, the contents of which are incorporated herein by reference in their entirety.

TECHNICAL FIELD

The subject matter described herein relates generally to a rotatable docking station for use in connection with a patient monitor.

BACKGROUND

During the course of providing healthcare to patients, practitioners typically monitor patient medical parameters of a patient using a monitoring device. These are usable by healthcare practitioners (e.g., nurses, doctors, physician assistants, or any other person charged with providing a healthcare service to a patient) in monitoring a patient and determining a course of healthcare to be provided to the patient. Patient monitoring devices can be selectively connected to the patients at any point during which a healthcare professional comes into contact with the patient and thus can remain connected with the patient as the patient moves through various locations within a particular healthcare enterprise (e.g. hospital) or between different healthcare enterprises (e.g. different medical facilities). Once it is determined that a patient is to remain in a fixed location, the patient monitoring devices are selectively connected (docked) to a docking station that can serve as a gateway for connecting the patient monitoring device to a hospital information system (HIS) and/or central monitoring station and allowing data representing the at least one patient medical parameter to be communicated to other systems within the healthcare enterprise.

SUMMARY

In one aspect, an apparatus includes a base component having a center axis and at least two index positions, a rotational component coupled to the base component configured to circularly maneuver about the center axis between the at least two index positions, a docking receptacle coupled to the rotational component configured to receive a monitor having an electronic visual display, and a handle configured to facilitate maneuvering of the rotational component.

In some variations, the monitor can be a patient monitoring device. The patient monitoring device can be coupled to at least one physiological sensor measuring one or more physiological parameters of a patient. The one or more physiological parameters can be provided by the at least one physiological sensor. The patient monitoring device can be configured to display one or more physiological parameters provided by the at least one physiological sensor on the electronic visual display.

In other variations, the apparatus can further include a power supply internal to the base component configured to provide power to the monitor when docked in the docking receptacle.

In some variations, the apparatus can further include an index mechanism having a locking component. The index mechanism can be configured to engage the locking component to selectively maintain a position of the rotational component at one of the at least two index positions. The index mechanism can disengage the locking component based on a user interacting with the handle. The user interacting with the handle can include gripping the handle. Alternatively, the user interacting with the handle can include touching the handle. The handle can be configured to receive a grip from a male user or a female user having an anthropometric profile between a fifth percentile and a ninety-fifth percentile.

In other variations, the apparatus can further include a sliding shroud configured to cover the docking receptacle in absence of the monitor being docked. The sliding shroud can protect a docking connector within the docking receptacle. The sliding shroud can be further configured to retract away from the docking receptacle.

In some variations, the rotational component can be further configured to prohibit movement to one of the at least two index positions based on the monitor being docked in the docking receptacle. The at least two index positions can be spatially separated indices of about 90 degrees. The at least two index positions can be defined by magnetic positional stops. Alternatively, the at least two index positions can be defined by mechanical positional stops.

In other variations, the base component, rotational component, the docking receptacle, and the handle can each include ergonomic radii to facilitate cleaning about the ergonomic radii.

In some variations, the apparatus can further include an electrical connection to the base component configured to provide power to the monitor.

In other variations, the apparatus can further include an electrical connection to the base component configured to facilitate transmission of data to the monitor.

In some variations, the base component can further include at least three index positions.

The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.

The subject matter described herein provides many technical advantages. For example, the rotatable docking station as described herein provides positioning of a docking station in various index positions without having to move the entire docking station. A rotatable component of the docking station, as described herein, provides for docking of a patient monitor in one or more index positions facilitating right and left handed docking. Additionally, an ergonomic handle design allows for such rotation to be made by a user using a single hand.

DETAILED DESCRIPTION

Selectively docking a patient monitoring device to a docking station can allow for power and/or data transmission between the patient monitoring device and the docking station. A rotatable docking station can provide for docking of a patient monitoring device in various index positions to facilitate usability of the docked monitor. More specifically, the rotating docking station can have a rotatable component that can be circularly maneuvered about a 360 degree rotational axis using a mechanical or magnetic index mechanism.

<figref idref="DRAWINGS">FIG. 1</figref> is a logic diagram <b>100</b> illustrating a monitor <b>120</b> and a rotatable docking station <b>160</b>. <figref idref="DRAWINGS">FIGS. 2, 4-8</figref> are diagrams providing various views <b>200</b>, <b>400</b>-<b>800</b> of example implementations of the monitor <b>120</b> and the rotatable docking station <b>160</b>. While certain configurations are illustrated with regard to the rotatable docking station <b>160</b> and the monitor <b>120</b>, it will be appreciated that these illustrations in <figref idref="DRAWINGS">FIGS. 2 and 4-8</figref> are examples and not limiting in nature (unless otherwise specified).

The monitor <b>120</b> can, for example, be a patient monitor that is used to monitor various physiological parameters for a patient <b>110</b>. With such a variation, the monitor <b>120</b> can include a sensor interface <b>122</b> that can be used to connect via wired and/or wireless interfaces to one or more physiological sensors and/or medical devices via one or more cables <b>112</b> (e.g., ECG electrodes, SPO2 sensor, blood pressure cuffs, apnea detection sensors, respirators, etc.) associated with the patient <b>110</b>. The monitor <b>120</b> can include one or more processors <b>124</b> (e.g., programmable data processors, etc.) which can execute various instructions stored in memory <b>130</b> of the monitor <b>120</b>. Various data and graphical user interfaces can be conveyed to a user via an electronic visual display <b>126</b>. This information can, for example, relate to the measured physiological parameters of the patient <b>110</b> and the like (e.g., blood pressure, heart related information, pulse oximetry, respiration information, etc.). Other types of information can also be conveyed by the electronic visual display <b>126</b>. In some variations, the electronic visual display <b>126</b> includes a touch screen interface.

The monitor <b>120</b> can additionally include a communications interface <b>128</b> which allows the monitor <b>120</b> directly or indirectly (via, for example, the rotatable docking station <b>160</b>) to access one or more computing networks. The communications interface <b>128</b> can include various network cards/interfaces to enable wired and wireless communications with such computing networks. The communications interface <b>128</b> can also enable direct (i.e., device-to-device, etc.) communications (i.e., messaging, signal exchange, etc.) such as from the rotatable docking station <b>160</b> to the monitor <b>120</b>.

The monitor <b>120</b> can optionally also include a power source and/or conduit <b>132</b> that can be used to power the various components of the monitor <b>120</b>. The power source/conduit <b>132</b> can include a self-contained power source such as a battery pack and/or it can include an interface to be powered through an electrical outlet (either directly or by way of the rotatable docking station <b>160</b>).

The rotatable docking station <b>160</b> can include one or more processors <b>162</b> (e.g., programmable data processors, etc.) which can execute various instructions stored in memory <b>164</b> of the rotatable docking station <b>160</b>. The rotatable docking station <b>160</b> can additionally include a communications interface <b>166</b> which allows the rotatable docking station <b>160</b> directly or indirectly to access one or more computing networks. The communications interface <b>166</b> can include, various network cards/interfaces to enable wired and wireless communications with such computing networks. The communications interface <b>166</b> can also enable direct (i.e., device-to-device, etc.) communications (i.e., messaging, signal exchange, etc.) such as with the monitor <b>120</b>.

The rotatable docking station <b>160</b> can optionally also include a power source and/or conduit <b>168</b> that can be used to power the various components of the rotatable docking station <b>160</b> and/or the monitor <b>120</b> when secured to the rotatable docking station <b>160</b>. The power source/conduit <b>168</b> can include a self-contained power source such as a battery pack and/or it can include an interface to be powered through an electrical outlet.

In some variations, the processors <b>162</b> and the memory <b>164</b> are omitted such that the rotatable docking station <b>160</b> provides only physical support and optionally a power source.

The rotatable docking station <b>160</b> has a shape and size which allows it to detachably secure the monitor <b>120</b>. In this regard, detachably secure means that the rotatable docking station <b>160</b> can secure the monitor <b>120</b> such that it can be removed by a user when desired.

The rotatable docking station <b>160</b> can include a coupling <b>170</b> that allows the monitor <b>120</b> to be secured at such location. The coupling <b>170</b> can include a combination of ledges, rails, ribs, abutments, latches, and the like to allow the monitor <b>120</b> to be secured to the rotatable docking station <b>160</b>. The coupling <b>170</b> can additionally or alternatively use different securing mechanisms including magnetic and/or electromagnetic locking mechanisms which cause the monitor <b>120</b> to selectively be secured by the rotatable docking station <b>160</b>. In some cases, the monitor <b>120</b> can slide into and out of the coupling <b>170</b> from a lateral direction (i.e., from the side of the rotatable docking station <b>160</b>) while in other variations, the monitor <b>120</b> can be placed on and removed from the forward face of the rotatable docking station <b>160</b>. In some implementations, the monitor <b>120</b> can both slide into and out of the coupling <b>170</b> from the lateral direction and be placed on and removed from the forward face of the rotatable docking station <b>160</b>.

The positioning of the monitor <b>120</b>, when secured to the rotatable docking station <b>160</b>, can be such that the communications interface <b>128</b> on the monitor <b>120</b> lines up to the communications interface <b>166</b> of the rotatable docking station <b>160</b> to allow, for example, a direct electrical connection. In other variations, the communications interface <b>128</b> of the monitor <b>120</b> exchanges data with the communications interface <b>166</b> of the rotatable docking station <b>160</b> optically (via, for example, respective optical windows on the monitor <b>120</b> and the rotatable docking station <b>160</b>).

The positioning of the monitor <b>120</b> when secured to the rotatable docking station <b>160</b> can also align the power source/conduit <b>132</b> of the monitor <b>120</b> to be coupled to the power source/conduit <b>168</b> of the rotatable docking station <b>160</b> which causes the rotatable docking station <b>160</b> to power the monitor <b>120</b>.

<figref idref="DRAWINGS">FIG. 2</figref> is a perspective view of a rotatable docking station <b>200</b> having a base component <b>210</b>, rotational component <b>220</b>, docking component <b>230</b>, and optional physiological parameter measurement pod rack <b>250</b>. Base component <b>210</b> can include a rotational component <b>220</b> coupled thereto and an internal power supply (not shown) that can provide power to a detachably coupled monitor <b>120</b>. Physiological parameter measurement pod rack <b>250</b> can include one or more bays for docking of one or more physiological parameter measurement pods <b>252</b>, <b>254</b>. Physiological parameter measurement pods <b>252</b>, <b>254</b> are devices for measuring one or more patient physiological parameters. Additionally physiological parameter measurement pods <b>252</b>, <b>254</b> can facilitate the exchange of data related to the physiological parameters with a patient monitoring device, such as monitor <b>120</b>. Physiological parameter measurement pod rack <b>250</b> can also include additional input/output ports at the rear of its housing (not shown). When docked within physiological parameter measurement pod rack <b>250</b>, the one or more physiological parameter measurement pods can transmit and/or receive data and/or power from physiological parameter measurement pod rack <b>250</b>.

Docking component <b>230</b> can be coupled to rotational component <b>220</b>. Docking component <b>230</b> can include a docking connector <b>232</b> and docking receptacle <b>236</b>. A monitor <b>120</b>, such as a patient monitoring device, can be docked within docking component <b>230</b> into docking receptacle <b>236</b>. When docked into docking receptacle <b>236</b>, monitor <b>120</b> can be locked into place by docking connector <b>232</b> and/or other mechanical features of docking component <b>230</b> (e.g., ledges, rails, ribs, abutments, latches, and the like to allow the monitor <b>120</b> to be secured within docking component <b>230</b>). Docking connector <b>232</b> can facilitate the transfer of power and/or data between rotatable docking station <b>200</b> and a detachably coupled monitor <b>120</b>.

Docking component <b>230</b> can also include a handle <b>234</b> located on one side opposite of the docking receptacle <b>236</b>. Handle <b>234</b> can be ergonomically sized to accommodate various hand sizes (e.g., having an anthropometric profile between approximately 5th percentile to 95th percentile). A user can interact with handle <b>234</b>, for example, via touching and/or gripping the handle (e.g., using a single hand) to circularly maneuverer the rotatable component <b>220</b>. In some variations, handle <b>234</b> can include electrical and/or mechanical features to sense the touching and/or gripping of a user. Such electrical and/or mechanical features can prohibit movement of the rotational component <b>220</b> when a monitor <b>120</b> is docked within docking receptacle <b>236</b>. Additionally, rotatable docking station <b>200</b> can have ergonomic radii that facilitates ease of cleaning.

Rotational component <b>220</b> can facilitate circular rotation about a center axis <b>260</b>. Rotational component <b>220</b> can circularly maneuver about a 360 degree rotation axis (e.g., center axis <b>260</b>) while base component <b>210</b> remains stationary. Such rotation can be in a clockwise and/or a counter-clockwise circular direction. In some variations, rotational component <b>220</b> can allow for circular maneuvering between an index position of 0 degrees and an index position of 180 degrees or 270 degrees due to various cable lengths of one or more cables <b>112</b>. An index mechanism (not shown) internal to base component <b>210</b> and rotational component <b>220</b> can facilitate such rotational movement. Rotational component <b>220</b> can stop at various, clinically relevant index positions (e.g., spatially separated by approximately 90 degree increments about a 360 degree axis, spatially separated by approximately 45 degree increments about a 360 degree axis). Rotational component <b>220</b> facilitates positioning of a detachably coupled monitor <b>120</b> to a position convenient for patient monitoring. For example, such convenience can include the positioning of the monitor to accommodate placement of cables coupled to the monitor <b>120</b> or positioning of the monitor based on hand preference of the user (e.g., nurses, doctors, physician assistants, or any other person charged with providing a healthcare service to a patient). User interaction with handle <b>234</b> can engage and/or disengage a locking component within the internal index mechanism into the various index positions. In some variations, the internal index mechanism can be a mechanical mechanism having mechanical detent locking components at the various index positions. In other variations, the internal index mechanism can be a magnetic mechanism such as magnetic positional stops, as discussed in detail with <figref idref="DRAWINGS">FIGS. 3A-3B</figref>.

<figref idref="DRAWINGS">FIG. 3A</figref> is a perspective view of an example magnetic index mechanism <b>300</b> having magnetic positional stops at various index positions. Index mechanism <b>300</b> can include T-shaft <b>310</b> mounted within base component <b>210</b> and a first securing magnetic ring <b>320</b>. First securing magnetic ring <b>320</b> can be correlated with second securing magnetic ring <b>340</b> of <figref idref="DRAWINGS">FIG. 3B</figref>. <figref idref="DRAWINGS">FIG. 3B</figref> is a perspective view of a first and second securing magnetic ring of the example magnetic index mechanism <b>300</b> of <figref idref="DRAWINGS">FIG. 3A</figref>. The second securing magnetic ring <b>340</b> can be internally mounted within rotational component <b>220</b>. The first and second securing magnetic rings <b>320</b>, <b>340</b> can be electromagnets, e.g., multi-pole correlated magnetic structures, that are pre-programmed to result in varying resistance as they are rotated with respect to one another. The magnetic attraction between the first securing magnetic ring <b>320</b> and second securing magnetic ring <b>340</b> can facilitate the rotational movement of rotational component <b>220</b>. The magnetic interaction between the first and second securing magnetic rings <b>320</b>, <b>340</b> can replicate a tactile feeling (to a user) of a spring force that acts against the rotation of rotatable component <b>220</b>. Such tactile feeling can represent a torsional resistance felt by a user that increases as the rotational component <b>220</b> approaches one of the index positions (e.g., 45 or 90 degree increments of a 360-degree axis).

<figref idref="DRAWINGS">FIGS. 4A-4C</figref> are perspective views <b>400</b>, <b>420</b>, <b>430</b> of a rotatable docking station <b>400</b> having a sliding shroud <b>410</b>. As illustrated in <figref idref="DRAWINGS">FIG. 4A</figref>, sliding shroud <b>410</b> can cover at least a portion of docking receptacle <b>236</b> in absence of a monitor <b>120</b> being docked within docking receptacle <b>236</b>, in order to prevent particle and/or liquid contamination. For example, such contamination can be caused by an ingress of moisture and/or particulates, such as dust and/or water. More specifically, the sliding shroud <b>410</b> can protect the docking connecter <b>232</b> within docking receptacle <b>236</b>. The protection provided by sliding shroud <b>410</b> can facilitate electrical connections between a monitor <b>120</b> and docking connector <b>232</b>. Sliding shroud <b>410</b> can cover at least a portion of docking connecter <b>232</b>, for example, when rotatable docking station <b>160</b> is not in use. Sliding shroud <b>410</b> can retract into the docking receptacle <b>236</b> towards docking connector <b>232</b> in order to expose docking connector <b>232</b> when a monitor <b>120</b> is being coupled to docking receptacle <b>236</b>. For example, an act by a user to mount a monitor <b>120</b> into docking receptacle <b>236</b> can cause sliding shroud <b>410</b> to mechanically retract into docking receptacle <b>236</b>, absent any additional act by the user, so as to expose docking connector <b>232</b>, as illustrated in perspective view <b>420</b> of <figref idref="DRAWINGS">FIG. 4B</figref>. For illustration purposes, <figref idref="DRAWINGS">FIG. 4B</figref> illustrates a transitional view of sliding shroud <b>410</b> partially retracted to expose a portion of docking connector <b>232</b>. When monitor <b>120</b> is fully docked within docking receptacle <b>236</b>, sliding shroud <b>410</b> can fully expose docking connector <b>232</b>, as illustrated in perspective view <b>430</b> of <figref idref="DRAWINGS">FIG. 4C</figref>. The direct mechanical force of monitor <b>120</b> being docked within docking receptacle <b>236</b> causes sliding shroud <b>410</b> to retract into docking receptacle <b>236</b>, exposing docking connector <b>232</b>. Sliding shroud <b>410</b> can include one or more spring mechanisms which facilitate covering of docking connector <b>232</b> when monitor <b>120</b> is absent from docking receptacle <b>236</b>. The one or more spring mechanisms internal to the sliding shroud <b>410</b> can be compressed during the docking of the monitor <b>120</b> within docking receptacle <b>236</b>. Note that for illustration purposes, the monitor <b>120</b> that is being docked within docking receptacle <b>236</b> is not illustrated in <figref idref="DRAWINGS">FIG. 4B</figref> or <figref idref="DRAWINGS">FIG. 4C</figref>. When the monitor <b>120</b> is removed from docking receptacle <b>236</b>, the one or more spring mechanisms within sliding shroud <b>410</b> decompress, causing the sliding shroud <b>410</b> to cover docking connector <b>232</b> as illustrated in <figref idref="DRAWINGS">FIG. 4A</figref>.

<figref idref="DRAWINGS">FIG. 5</figref> is a perspective view of an example rotatable docking station <b>500</b> having a monitor <b>120</b> detachably coupled to docking receptacle <b>236</b> of <figref idref="DRAWINGS">FIG. 2</figref> indexed at a 0 degree position. As illustrated in <figref idref="DRAWINGS">FIG. 5</figref>, monitor <b>120</b> is positioned such that one or more connection ports <b>510</b> are on the left hand side of rotatable docking station <b>500</b>. Such orientation can facilitate, for example, a right-handed touching and/or gripping of handle <b>234</b> to circularly maneuver the rotational component <b>220</b> to another index position. The one or more cables <b>112</b> can be coupled to the one or more connection ports <b>510</b> to facilitate transmission of physiological parameters of patient <b>110</b> to monitor <b>120</b>.
